铝电解用NiO/Fe梯度功能电极的制备及其腐蚀行为姚同路1,林平1,秦庆伟2(1.北京市钢铁研究总院冶金工艺研究所2.武汉科技大学 材料与冶金学院,武汉 430081)摘 要:采用传统粉末冶金技术制备铝电解用NiO/Fe金属陶瓷惰性阳极,并研究其在Na3AlF6-Al2O3熔体中的腐蚀行为.结果表明,金属Ni与NiO陶瓷的润湿性能较好,NiO/Fe金属陶瓷的致密化容易实现,表现出相对好的耐蚀性.当分子比=2.3和氧化铝浓度近饱和时电极腐蚀率最小.关键词:复合材料; 梯度功能材料; 铝电解; 惰性阳......

electrowinning for preparation of Al-Ni master alloys. The electrolysis tests were carried out in Na3AlF6-Al2O3 based melts at 940 ℃. The results show that the cell voltage during electrolysis has only minor instability, and there exists NiO phase in electrolyte after 0.5 h electrolysis. Ni content in Al-Ni master alloys increases with increasing the electrolysis time. Concentration limit of Ni in Al-Ni......
